How we handle gutter sealing in Wimbledon
For gutter sealant to hold, the joint has to be clean and dry. That’s why we take out the old sealant and dirt first and the joint is dried before the new sealant goes in. Common call-outs are for water dripping where gutter sections meet and end caps that drip every time it rains, on gutter end caps, gutter joints and garage door frames.
Working on the outside of a London home means planning access: shared paths, upper floors and parking. For a home in Wimbledon, tell us how high the joints are and how to reach the back of the building.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes anything from an hour or two to a few hours, depending on the size of the job. In Wimbledon, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We find where the water is coming from and check the gutter is sound.
- The old sealant and dirt are cleaned out of the joint.
- We dry the joint so the new sealant can bond.
- We seal the joint with a sealant made for gutters.
- We check the run and clear debris near the joints.
How to prepare
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises

What the job involves on each surface
Roofline trims
We seal the trims, not the roof. A roofer deals with the roof itself.
Garage door frames
Resealing a garage door frame keeps rain and draughts out.
What we are called out for in Wimbledon
Sagging sections pull joints apart. Sealing won’t hold if the gutter keeps dropping so the brackets need attention first.
Look out for any of the following:
- Internal damp traced to a gutter joint
- Earlier gutter repairs that have peeled off
- Water running down the wall below the gutter
- Rain getting in around a garage door
As a London address, Wimbledon can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Looking after it afterwards
After the cure time, these simple habits help:
- Keep downpipes clear
- Look at the gutters while it’s raining
- Rest ladders on the wall, not the gutter
- Deal with a drip before winter
Clear the gutters once or twice a year so water does not sit on the joints. Water left in a gutter tests every joint.
If an end cap is dripping, deal with it before winter. Water down the wall all winter can cause damp inside.
What gutter sealing looks like in Wimbledon
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Southside House (about 1.1 miles south-west) nearby, there’s older building stock in the area around Wimbledon as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For site and facilities teams at buildings such as Wimbledon High School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Wimbledon station? Then a gutter joint that drips onto the wall can turn into a damp complaint, so it’s worth checking.
